Description

Technical Field

[0001] The invention relates to the technical field of gold plating, and in particular to a gold plating device and a gold plating process for a contact of an aviation electrical control connector. Background Art

[0002] With the development of electronic products, electronic connectors (also known as electronic connectors) are used more and more widely. As an electronic connector, its basic functions can be divided into two categories: signal transmission and electrical transmission. Regardless of which type of transmission, its characteristic is that there must be current passing through the terminals that are in contact with each other. This feature requires that the contact resistance between the two contacts is as small as possible to ensure that the signal or amount of electricity transmitted is not affected. Especially when completing signal transmission, the voltage of signal transmission is generally very small. When the contact resistance between the two contact terminals is too large, the signal is weakened or distorted. Usually we plate a gold layer with high conductivity on the two contact terminals to reduce the contact resistance between them. However, as a connector, a significant feature of its use is that it is often plugged and unplugged, and there is often friction between the two contacts. When plugged and unplugged a certain number of times, the gold layer on the surface of the contact will be worn away, and its contact resistance will increase, affecting the transmission of the signal.

[0003] A Chinese patent with announcement number CN110284164B discloses a gold plating solution for a pin socket of an electronic connector and an electroplating device thereof, wherein the gold plating solution is composed of raw materials in the following proportions: 9-11 g / L potassium cyanogen gold, 34-36 g / L potassium citrate, 34-36 g / L citric acid, 34-36 g / L sodium allyl sulfonate, 0.4-0.6 g / L thiourea, 1-3 g / L malononitrile, 0.01-0.015 g / L 2.2-bipyridine, and 0.8-1.2 g / L ultrafine corundum; the gold plating solution adds a nano-scale ultrafine diamond, so that the gold plating layer contains a certain amount of nano-scale ultrafine diamond particles, which greatly improves the wear resistance of the gold plating layer, reduces the contact resistance between the contact pieces, and improves the reliability of the electrical connector.

[0004] However, the above disclosed solutions have the following shortcomings: the above solutions need to manually operate the gold plating process during use, thereby reducing the efficiency and accuracy of the batch gold plating production process. Summary of the invention

[0043] Embodiment 2

[0044] like Figure 1-Figure 4 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the above-mentioned embodiment 1, a gold plating process for the contact of an aviation electrical control connector includes the following steps:

[0045] The loading step is to install the contact piece that needs to be gold-plated in the limiting groove 408 in the above-mentioned device mounting plate 407. At this time, the metal contact point of the contact piece that needs to be gold-plated faces vertically downward. After the contact piece is installed in the limiting groove 408, the locking member 411 is unlocked to allow the abutting member 412 to slide freely. The abutting groove 413 clamps and limits the side of the contact piece from the side through the sliding of the abutting member 412, and the metal contact point that needs to be plated is located at the center of the abutting groove 413.

At this time, the abutting member 412 supports the contact piece from the side through the abutting groove 413 to prevent the contact piece from falling off during the gold plating process.

[0046] A circulation step, in which the electroplating liquid in the housing 1 is in a flowing state by starting the circulation pump 501. Before starting the circulation pump 501, there is still electroplating liquid in the housing 1. At this time, the electroplating liquid at the bottom can be sucked into the circulation pump 501 through the circulation pipe 502 by the suction force generated by the circulation pump 501 and then discharged from the top side of the housing 1, thereby realizing the circulation of the electroplating liquid;

[0047] The descending step can realize the descending effect of the lifting member 406 by rotating the threaded rod 403, so that the gold-plated part of the contact fixed in the above step is in contact with the electroplating liquid inside the shell 1. Due to the insulating layer on the surface of the threaded rod 403, the threaded rod 403 will not contact the electroplating liquid. The effect of the lifting and lowering adjustment is based on the full contact between the metal contact point and the electroplating liquid.

[0048] The electroplating step generates an electric current through the control module 301 so that the electroplating liquid inside the shell 1 is ionized and precipitated on the surface of the metal contact point, thereby achieving a gold-plating effect. After the control module 301 is started, negatively charged electrons enter the electroplating liquid through the conductive member 303, so that metal cations are precipitated. At the same time, the other end of the control module 301 connects the cable 304 and the docking member 305 so that several docking cables 306 are positively charged. At this time, the docking cable 306 is connected to the contact member through the through hole 409, so that there is a positive charge on the surface of the contact member, thereby attracting the precipitated metal ions to be enriched on the surface of the metal contact point, thereby achieving a gold-plating effect.
